Does it happen ONLY with that game, and ONLY that drive? Cause that to me looks like it's your video card. Did this always happen or just recently? and what were the settings on the game if it just started happening? did you max them out trying for a better picture? Cause even if that PSU is proprietary, it should handle what you have no problem... IMO but then I don't know how old it is, condition, use, etc...
